Supramolecular polymers bearing disulfide bonds†
Abstract
This work is aimed to report a new type of multiple stimuli-responsive supramolecular polymers by combining dynamic covalent bonds with cucurbit[8]uril (CB[8])-based host–guest interaction. Supramonomer (DSN) containing a disulfide bond can bind with CB[8] to fabricate supramolecular polymers by host-enhanced π–π interaction. Additionally, the dynamic nature of disulfide bonds and host–guest chemistry endow these supramolecular polymers with redox and guest competitive responsiveness, respectively.
